Hi Ben - sorry for taking so long to reply.  I'm currently using Ardour
version 2.0.5, revision 2513.  I could send you a small sample if you want
to verify this with a more recent version.

I still need to understand the relationship between fades and crossfades -
in particular, what should happen if a fade and a crossfade co-exist at
the same point in a playlist.  For example, if 2 regions overlap (with let's
say a 1 second crossfade) but the outgoing region also has a (2 second)
fade-out, how does Ardour handle this - e.g.

1)  Does Ardour combine the fade and the crossfade audibly; or,
2)  Does the fade-out stop playing when the crossfade starts playing? (in
other words, are a fade and crossfade mutually exclusive?)

Another grey area is 'normalized' audio.  The gain values for a crossfade
always seem to be in the range from 0 to 1, where '1' happens to correspond
to the scale-gain for a non-normalized timeline region (i.e. unity gain).
But is that '1' significant?  If the outgoing region was normalized, would
the crossfade now assume '1' to be the 'normalized' gain or would the
crossfade stilll start the outgoing segment from unity gain?

Thanks,


John
